Clever Gardening Technique

Plant Small Rootballs
Research shows that smaller-sized tree transplants (15 gallon) catch up to larger transplants (24-inch boxes) within about five years. The big trees suffer more transplant shock to their larger root system so their growth rate is slowed. Save yourself labor and money by planting a smaller tree. It's much easier to dig a hole for a smaller rootball!

Low-Water Trees
To help you select trees that will thrive in your landscape, check out Low-Water Trees, a list of trees adapted to the Southwest that will do well with a minimum of supplemental water. Put together by the Arizona Municipal Water Users Association, it contains much helpful information about 44 kinds of trees, including mature size; growth rate; whether the tree is allergenic, has thorns, or drops litter; water needs; cold hardiness; attractiveness to wildlife; and where the tree is native, as well as a picture. A great resource for water-conscious gardeners!
